Description
Technical field
The utility model relates to a kind of electrode holders.
Background technology
Electrode holders are a kind of instruments commonly used, are suitable for more being suitable for for making it, and people improve it.As disclose on the utility model patent communique on October 9th, 1991 a kind of " safe lightweight electrode holders " (patent No. 91200523.8) its to the effect that: it is that the tail end that connecing cable is positioned at insulated handle and clamping face is between the copper energising guide rod on plane and the movable depression bar that jaw has two clamping faces (or rib) and is provided with spring and joint, and form caliper by a fixed pivot axis, it is characterized in that: the insulating materials that movable depression bar metal jaw outside coats fuses with the corresponding insulation depression bar of energising guide rod changeover portion with extending to handle notch place, can be equipped with the semi-transparent hole that is enclosed within the pin upper spring in establishing on its position relative with energising guide rod pin.Its weak point is: when welding rod is clipped between above-mentioned energising guide rod leading portion jaw and the movable depression bar metal jaw, because the welding rod outside is surrounded by welding agent, have only that the end is a bit of an exposed metal/bare metal, though being at 3 with welding rod one end, electrode holders contact, but really contact the fork pawl that good point has only movable depression bar jaw, and have welding agent to be separated by between the jaw of another fork pawl of movable depression bar jaw and energising guide rod and the welding rod, contact bad.When these electrode holders in when work, from the electric current of cable along the energising guide rod to the jaw of its leading portion, because the obstruct of welding agent, electric current can not directly enter welding rod, but pass on the jaw of movable depression bar by journal stirrup oblique crank Z joint, pass on the welding rod again by contact a good fork pawl with welding rod then.Because welding current is very big, can cause electrode holders heating, dangerous, poor practicability.
Summary of the invention
The purpose of this utility model be to provide a kind of structure more rationally, do not generate heat during work, rod shape bikini electrode holders safe in utilization.
The utility model is based on prior art, and the metal jaw of energising guide rod leading portion jaw and movable depression bar is improved.The utility model mainly is made of energising guide rod, movable depression bar and insulated handle.Copper energising guide rod is strip, and leading portion is provided with the jaw of welding rod, and it is the fork-shaped jaw with two clamping faces (or rib), and it can be used as two stress points of welding rod.Best two fork pawl bottoms are linked to each other by connecting plate, and the three constitutes the groove that front end has opening, and first welding rod can enter in the jaw in the opening insertion groove again, makes things convenient for clamping of welding rod like this.Be provided with the journal stirrup of vertical clamping face in the back of this energising guide rod jaw, establish axis hole on the journal stirrup.On the energising guide rod of journal stirrup back, be provided with the pin of vertical clamping face, can be with spring on it and be located.The outside of above-mentioned energising guide rod leading portion is coated with the insulating materials shell, and section is positioned at the tubular handle of being made by insulating materials thereafter.Front portion at energising guide rod back segment is provided with screw, is provided with pin for suppressing metal in it, and the tail end that rotates this pin energising guide rod upwarps, and will switch on guide rod and handle are fixed together.Establish the securing member that cable is linked to each other with the energising guide rod in the pin for suppressing metal back.Preferably switch on guide rod the front and back section not at grade, be stairstepping, and the back segment that is positioned at handle is near apart from the leading portion that the distance of caliper center line is positioned at outside the handle, coupled movable depression bar position is moved down, behind the clamping welding rod, movable depression bar afterbody is just near relatively from handle center's line, has so not only solved movable depression bar afterbody and has exceeded the problem of handle but also solved the problem that the guide rod leading portion of switching on is not higher than handle.Movable depression bar of the present utility model is still by the metal jaw and is coated on its outside depression bar and constitutes, and its main part is straight-bar substantially, and wherein metal jaw middle part is provided with the journal stirrup of vertical clamping face, and its journal stirrup with the energising guide rod is corresponding.Establish bearing pin in both axis holes, its will switch on guide rod and movable depression bar are movably connected to form caliper.The metal jaw of movable depression bar journal stirrup front portion is one, and its cross section can be a triangle, trapezoidal, semicircle, inverted T-shaped preferably, and it is a clamping face with the relative side of guide rod of switching on.This retained part that is the plane can be used as another stress point of welding rod.This metal jaw outside coats the depression bar of being made by insulating materials, and it extends to notch place on the handle always.Preferably the position that depression bar is relative with pin on the energising guide rod is provided with circular slotted eye, and the spring other end that is enclosed within on the pin places in it.This spring under normal conditions not pressurized be in free state, after jaw folder was gone up welding rod, the metal jaw was subjected to a power that makes progress, by this fulcrum of journal stirrup bearing pin, spring is subjected to a downward power, is in pressured state, the reaction force of spring impels the jaw closure again, so that welding rod is clamped.The position relative with energising guide rod pin is provided with the through hole that can insert screwdriver at the depression bar rear portion in addition.
As long as the utility model is when the clamping welding rod, and the welding rod exposed part will contact well with a fork pawl of energising guide rod jaw, and electric current will directly pass on the welding rod along this path, because circuit is smooth and easy, electrode holders just can not generate heat; And the metal jaw of movable depression bar mainly works the effect of gripping, and contacts to guarantee electrode holders and welding rod 3.
The utility model has following advantage compared to existing technology:
1 makes current trend reasonable, has reduced an ear portions heating, not only safe but also can increase service life.
Behind 2 these electrode holders clamping welding rods, movable depression bar afterbody no longer exceeds handle, the fundamental sum handle on a face, hand-held comfortable, use flexible, practical.
3 utilize the slit of former welding rod to sandwich new welding rod, and welding rod is changed more efficient and convenient, both reduces labor intensity, and improves work efficiency again.
